Preparation of ruthenium/iron catalysts supported on carbon |
September 5, 2006 |
| The present invention relates to a process for the preparation of iron-doped ruthenium catalysts supported on carbon, and their use for the selective liquid phase hydrogenation of carbonyl compounds to give the corresponding alcohols, in particular for the hydrogenation of citral to |

Finely divided acicular magnetic modified chromium dioxide |
October 29, 1996 |
| A finely divided acicular CrO.sub.2 modified with iron, tellurium and/or antimony and having a high coercive force possesses improved heat stability of the residual induction and a relatively narrow distribution of the particle size and of the coercive force. This CrO.sub.2 pigment is |

Preparation of acicular cobalt-containing magnetic iron oxide |
January 16, 1996 |
| Acicular cobalt-containing magnetic iron oxides having a high coercive force and a core/shell structure and hence low temperature dependence of the coercive force are prepared by a process in which, in a first stage, surface activation is effected by means of iron(II) and cobalt ions und |
